Here is an Arduino based circuit with three independent pulse width modulated (PWM) channels to fulfil your requirements! Just follow the schematic diagram to complete the ... current loads -the ...

It is a pretty common first project to use an Arduino ... Blinking an LED with three resistors and a capacitor. Ok, ok… one of the resistors is a light-dependent resistor, but still.

Furthermore, the vacant solder pads near the three-pin interface header is for mounting a light-dependent resistor ... translucent project enclosure. Otherwise, remove it from the board and wire an ...
